Sewage Defence

Sewage Defence

Sewage back flow causes untold damage, has long-term consequences and means high clean up expenses.

Prevent contamination from sewage and waste water with passive and automatically deployed solutions.

The Flood Angel 160mm/110mm Non-Return Valve

The Flood Angel 160mm/110mm Non-Return Valve is the UK's only adaptable non-return valve that gives the benefit of passive protection due to the integral self-activating flap powered by the flood water.

Under normal operating conditions the Flood Angel 160mm/110mm Non-Return Valve is fully open allowing solids to flow freely and unrestricted through the valve. In flood conditions when water surges back through the drainage system the gate is automatically deployed by the hydraulic pressure of the water. The gate is sealed against a neoprene gasket and this prevents back flow past the gate.

Inspection and maintenance is made easy with a fully rod-able system and a clear inspection lid. Sewage back flow can cause untold damage resulting in long term consequences and high clean up expenses. This can be prevented using this simple yet effective product.

Flood Angel Approved Sumps & Pumps

The pump and sump system sits below the ground floor to pump out water which enters through the ground. The pump removes water at a faster rate than it can enter. If the pump and sump is located in a protected zone the outlet is routed to an unprotected zone.

The benefit to this method of external installation removes excessive upheaval to the property owners and the subsequent costs caused by internal installation, which would otherwise require the joist to be cut out and supported. External installation allows easy access via a manhole cover, removing the need for large access space through an internal trapdoor and the associated disruption.
